Calculation of Pourbaix ... WebUsing the E 1 O, E 2 O, pK a, 1, and pK a, 2 values defined in Figure 4, for a PCET process, we can plot the famous Pourbaix diagram in which the regions of stability of each of the species Ox, OxH, Red, and RedH are defined . It should be recognised, however, that the boundaries between each of these regions do not represent step functions but represent …

Webconsidered species over the specified electrochemical phase space (E SHE ∈[−2, 3] V and pH 2, 16]), leading to the simulated Ni Pourbaix diagram. Additional details of the procedure to generate the Pourbaix diagram are given in ref 44. Samples and Solutions. Pure Ni (99.99 wt %) samples are prepared using standard metallographic techniques ... WebTo plot a Pourbaix diagram the relevant Nernst equations are used. As the Nernst equation is derived entirely from thermodynamics, the Pourbaix diagram can be used to determine which species is thermodynamically stable at a given E and pH. It gives no information about the kinetics of the corrosion process. Constructing a Pourbaix Diagram : frcc human resources
